About this map

The Columbia River carves through the dramatic basalt gap of the Horse Heaven Hills at the border of Benton and Walla Walla counties. This 2020 survey documents the modern confluence where the Walla Walla River meets Lake Wallula, an area historically significant for its river-and-rail navigation. The settlement of Wallula sits north of the river mouth, while Wallula Junction and the Madame Dorion Bridge serve as critical transit points across the water.

Industrial and agricultural transport infrastructure is evident in the presence of Port Kelley and the rail-aligned hamlets of Attalia and Yellepit. The map details the complex shoreline including Smiths Harbor, Badger Island, and Crescent Island, alongside irrigation works like Columbia Canal Number 3. The terrain rises sharply from the riverbanks to local heights such as Clover Hill and the distinctive Twin Sisters formation, illustrating the transition from the fertile river valley to the high plateau.
